My DS is 12 - he would love it! He wears black all year long, and we live in Texas. He never seems to be too hot. I bet Jackson will be fine - and he's gonna love this shirt!
I got the plain Imagine. It may be poor insight on my part, but I didn't particularly love the wave part - at least enough to pay the extra for it. I think it's really cute, but I kept thinking that I could use variagated thread for a similar affect. So, I cheaped out! There were a few things on the evolve that I loved, but, again, not enough for me to pay the extra. It was a stretch for me. The reason I kept putting it off was that I didn't like the idea of paying more for a serger than I did for my sewing machine. SO, the evolve was not in the cards for me. I am going to be very pleased with the Imagaine, though. I can tell already!
A funny story - when I went back to pick it up, the owner of the store made a comment that really stumped me. I asked him what the price difference inthe imagine and the evolve were (just to make sure I didn't want to go all the way!). He told me. Then he said, "for you to be walking out of here with that machine, at your age, is pretty amazing!" I said, "so, are you saying I'm old?" "NO! I'm saying that most people don't decide they want to invest in this type of machine until they're much older." I found that comment to be very interesting. I WAS the youngest in the class. Not that that is a bad thing at all! I just found it pretty interesting. I just said, "WELL, I have the gift of recognizing quality very quickly!"
